HTTP Status Code: 205 - RESET CONTENT

The 205 response is similar to a 204, but the user agent is supposed to refresh their view back the the default state of the current document. This response code is sent after accomplishing request to tell user agent reset document view which sent this request.

The 205 (Reset Content) status code indicates that the server has fulfilled the request and desires that the user agent reset the "document view", which caused the request to be sent, to its original state as received from the origin server.

This response is intended to support a common data entry use case where the user receives content that supports data entry (a form, notepad, canvas, etc.), enters or manipulates data in that space, causes the entered data to be submitted in a request, and then the data entry mechanism is reset for the next entry so that the user can easily initiate another input action.

Since the 205 status code implies that no additional content will be provided, a server MUST NOT generate a payload in a 205 response. In other words, a server MUST do one of the following for a 205 response: a) indicate a zero-length body for the response by including a Content-Length header field with a value of 0; b) indicate a zero-length payload for the response by including a Transfer-Encoding header field with a value of chunked and a message body consisting of a single chunk of zero-length; or, c) close the connection immediately after sending the blank line terminating the header section.

HTTP Status Code: 200 - Ok

The request has succeeded. The 200 (OK) status code indicates that the request has succeeded. The payload sent in a 200 response depends on the request method. For the methods defined by this specification, the intended meaning of the payload can be summarized as: GET a representation of the target resource HEAD the same representation as GET, but without the representation data; POST a representation of the status of, or results obtained from, the action; PUT DELETE a representation of the status of the action; OPTIONS a representation of the communications options; TRACE a representation of the request message as received by the end server. Aside from responses to CONNECT, a 200 response always has a payload, though an origin server MAY generate a payload body of zero length. If no payload is desired, an origin server ought to send 204 No Content instead. For CONNECT, no payload is allowed because the successful result is a tunnel, which begin...

HTTP Status Code 402 - Payment Required

This response code is reserved for future use. Initial aim for creating this code was using it for digital payment systems however this is not used currently. Wikipedia Reserved for future use. The original intention was that this code might be used as part of some form of digital cash or micropayment scheme, but that has not happened, and this code is not usually used. As an example of its use, however, Apple's MobileMe service generates a 402 error ("httpStatusCode:402" in the Mac OS X Console log) if the MobileMe account is delinquent.

HTTP Status Code 406 - Not Acceptable

The target resource does not have a current representation that would be acceptable to the user agent, according to the proactive negotiation header fields received in the request, and the server is unwilling to supply a default representation. The server SHOULD generate a payload containing a list of available representation characteristics and corresponding resource identifiers from which the user or user agent can choose the one most appropriate. A user agent MAY automatically select the most appropriate choice from that list. However, this specification does not define any standard for such automatic selection. This response is sent when the web server, after performing server-driven content negotiation, doesn't find any content following the criteria given by the user agent. The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the reques...
